Also question is, are TV shows filmed all at once?
For a Live Audience show, each episode is filmed over one day (generally speaking) in front of a live audience. For a scripted drama or comedy NOT filmed in front a live audience, they generally film the whole season, one episode at a time, but will start airing the show before they have finished filming.
Furthermore, was how it's made Cancelled? It is Not Cancelled.
Also question is, how long is a TV season?
Thus, a "full season" on a broadcast network now usually runs from September through May for at least 22 episodes. A full season is sometimes split into two separate units with a hiatus around the end of the calendar year, such as the first season of Jericho on CBS.
How does a narrator work?
In the U.S. version, Brooks Moore and Zac Fine (Season 9–10, 2007–2008) are the narrators.
